An appliance for thermally processing granular material, especially for roasting food items such as coffee beans. The granular material lies on a perforated base through which gas flows upwardly to create a fluidized bed. The exhaust gas is fed to a cyclone separator for separation of entrained solid particles. Preferably, the base is located in an inner chamber which is at least partially enclosed in an outer chamber forming the cyclone separator. The exhaust gas is fed into a top opening of the outer chamber thereby providing a rotary gas flow. Alternatively, the base is located in an outer chamber in which at least the area above the base is designed as the cyclone separator. The outer chamber at least partially encloses an inner chamber through which gas is fed to create a rotary gas flow. In both cases, an extremely compact roaster design is realized.
In an appliance for the thermal processing of granular material, especially for roasting food items such as coffee beans, wherein the material to be processed lies on a perforated base (11), a gas flows through said base from below creating a fluidized bed, and the exhaust gas is fed from said fluidized bed to a cyclone separator for separation of entrained solid particles, the improvement comprising said base (11) being located in an inner chamber (12) which is at least partially enclosed in an outer chamber (13) forming the cyclone separator, and the exhaust gas being fed into a top of said outer chamber in a rotary flow (16).
In an appliance for the thermal processing of granular material, especially for roasting food items such as coffee beans, wherein the material to be processed lies on a perforated base (31), a gas flows through the base from below creating a fluidized bed, and the exhaust gas is fed from said fluidized bed to a cyclone separator for separation of entrained solid particles, the improvement comprising said base (31) being located in an outer chamber (32) in which at least an area above said base is designed as a cyclone separator, said outer chamber at least partially enclosing an inner chamber (33) through which the gas is fed from beneath said base into said outer chamber in a rotary flow (36).
